Data Sources
Data Sources
LianShi catalog and recognition results are designed to speed up logging. They are not a medical-grade nutrition database and do not imply official brand authorization.
1. Catalog sources
Catalog entries may be based on public nutrition labels, package information, public store or brand information, common food references, user-confirmed values, and manual review.
Current catalog version, entry count, field coverage, and paginated search are available on the LianShi public catalog.
2. AI recognition
Photo recognition estimates food type, serving size, and nutrition information. Results should be reviewed and confirmed before being saved.
3. Public references
Goal calories, BMR/TDEE, protein targets, weight trend prompts, nutrition labels, and drink reminders reference public sources and are for everyday tracking only.

4. Brand names and logos
Brand names or logos are used only to help users search and log common food scenarios. Trademarks belong to their respective owners and do not imply partnership, authorization, sponsorship, endorsement, or official data access.
5. Accuracy
If LianShi data conflicts with package labels, store information, professional advice, or your measured result, use the latter. User-edited values take priority in personal logs.
